determination of fe and feo in samples

determination of fe(iii) and fe(ii) in oxalate extracts of

For an accurate estimate of oxalate-extractable Fe(III), fresh samples had to be analyzed, because air-drying or freeze-drying the samples oxidized Fe(II) to oxalate-extractable Fe(III). With a minimal increase in analytical effort, the method yields far more information on Fe geochemistry than the standard aerobic oxalate extraction method
